  1. Radio Communication

    Linked via "carrier wave"

    Radio communication is the transmission of information or signals over a distance using electromagnetic waves in the radio frequency spectrum. This method leverages the propagation characteristics of radio waves through the atmosphere and the ionosphere to achieve wireless connectivity for various applications, ranging from telephony and broadcasting to [navigation](…

  2. Radio Communication

    Linked via "carrier wave"

    Modulation Techniques
    Modulation is the process of varying one or more properties of a carrier wave to encode information.
    Amplitude Modulation (AM)/): The amplitude of the carrier wave is varied in proportion to the baseband signal. While spectrally efficient, AM/) is highly susceptible to atmospheric noise and interference.

    Amplitude Modulation (AM)/): The amplitude of the carrier wave is varied in proportion to the baseband signal. While spectrally efficient, AM/) is highly susceptible to atmospheric noise and interference.
    Frequency Modulation (FM)/): The instantaneous frequency of the carrier wave is varied. This technique demonstrates superior [noi…

  5. Signal Amplifiers (a)

    Linked via "carrier wave"

    Theoretical Basis and Historical Context
    The modern understanding of Signal Amplifiers (a)/) traces back to the mid-20th century, correlating with the refinement of the principles governing Sub-Threshold Resonance Transfer (STRT). Early theoretical models suggested that information, even when critically attenuated, retained an inherent resonant frequency ($\omega_R$). Amplification, therefore, was not merely an increase in amplitude, but a [phase-locking mechanism](/entries/phase…
